Journal ArticleDOI
Damage evaluation and deformation behavior of mine tailing-based Geopolymer under uniaxial cyclic compression
Nan Zhang,Ahmadreza Hedayat,Héctor Gelber Bolaños Sosa,Juan José González Cárdenas,Guido Edgard Salas Álvarez,Victor Benigno Ascuña Rivera +5 more
TL;DR: In this paper, the influence of NaOH molarity on the elastic and plastic strains of the geopolymer specimen at different cycles of cyclic loading has been explored, and the Young's modulus was found to increase followed by a decrease with the cycles for all the selected Naoh molarities.
Journal ArticleDOI
Specimen size effects on the mechanical behaviors and failure patterns of the mine tailings-based geopolymer under uniaxial compression
Nan Zhang,Ahmadreza Hedayat,Héctor Gelber Bolaños Sosa,Juan José González Cárdenas,Guido Edgard Salas Álvarez,Victor Benigno Ascuña Rivera +5 more
TL;DR: In this paper, the authors investigated the influence of the cubic specimen size on the compressive strength of mine tailings under unconfined compression and showed that the failure strain increased with the size of the sample.
Journal ArticleDOI
Estimation of the mode I fracture toughness and evaluations on the strain behaviors of the compacted mine tailings from full-field displacement fields via digital image correlation
Nan Zhang,Ahmadreza Hedayat,Héctor Gelber Bolaños Sosa,Jacob Tunnah,Juan José González Cárdenas,Guido Edgard Salas Álvarez +5 more
TL;DR: In this article, a series of semi-circular bending (SCB) tests were performed to examine the mode I fracture behavior of compacted MTs at different notch depths, and the digital image correlation (DIC) technique was utilized to acquire the surface image sequence under mode I loading condition in order to characterize the strain behaviors.
Fracture and Failure Processes of Geopolymerized Mine Tailings under Uniaxial Compression

Journal ArticleDOI
Isotropic compression behavior of granular assembly with non-spherical particles by X-ray micro-computed tomography and discrete element modeling
Nan Zhang,Ahmadreza Hedayat,Shaoyang Han,Shaoyang Han,Runlin Yang,Héctor Gelber Bolaños Sosa,Juan José González Cárdenas,Guido Edgard Salas Álvarez +7 more
TL;DR: In this article, X-ray computed tomography (μCT) and discrete element modeling (DEM) were utilized to investigate isotropic compression behavior of the granular assembly with regard to the particle morphological properties, such as particle sphericity, concavity and interparticle frictions.
